The present invention relates to improvements in tea-cartridges of thetype shown in Letters Patent #1,493,981, granted to me on May 13, 1924.In the Letters Patent mentioned, a device for extracting essence fromtea-leaves or coffee is described, com rising a tube of textile fabrichaving both ends drawn into folds, -a metal strip encircling andcompressing the folds'on each end ofthe 1o tube for closing said ends,and a suspending string held in place by both metal strips. Thesedevices, While comparatively easy to manufacture, have been foundobjectionable by the trade because of their form, the trade beinggenerally used to tea-cartridges the v container of which is in the formof an ordinary bag.

The main object of the present invention 1s in my above mentionedLetters Patent which,

however, is so shaped that it assumes the form of an ordinary bag. I Oneembodiment of the invention is illustrated in the accompanying drawings,in which v Figure 1 is a central vertical section taken through atea-cartridge constructed in accordance with the present invention; Fig.2 is an elevation of a tube of which the container of the said cartridgeis formed; Fi 3 is a similar elevation'of the said tube wit one ofitsends gathered into folds and with the suspending string attachedthereto; and ig. 4 is a section taken through the device shown in Fig.3, the tube being inverted.

In the drawings the numeral 10 indicates a tube of open-mesh textilefabric, such as cotton, it being made, for instance, of a single pieceof fabrlc, folded to form two plies, which are joined by a row ofstitches 12. In producing the cartridge, one end of the tube is gatheredinto folds to form a neck 13 (Fig. 3) andone end of a suspending string14 tied around the said neck, whereby a container 15 is formed. Thiscontainer is then inverted, as shown in Fig. 4; of the drawings, thesuspending string being extended centrally therethrough. Tea-leaves orcoflee for a n day of October,

singlebrewing are then glaced into the inverted container shown in ig.of the drawto provide a bag of the character described ings, after whichthe mouth of the container is gathered by puckering the same andapplying thereto a metal strip 16, which is shaped to assume the form ofa ring so as to prevent escaping of the contents of the ba To the freeend ofthe suspending string 1s attached in any suitable manner ahandle17 of pasteboard or like material. The sus-' pending stringextendsthrough the ring 16, it being clamped by the latter to the puckeredmouth portion thereof. Inasmuch as that portion of the string which isdisposed within the container is shorter than the height of the latter,it is obvious that the neck 14 on the bottom portion of the container isheld within and-concealed by the container, so

nary bag.

In some instances it may be desirable to extend the suspendin stringslidably through the ring 16, su cient friction being however maintainedbetween the mouth portion of the .bag and the said string to ordinarilymaintaln the container in the bag shape. The purpose of this arrangementis to permit the bag to be collapsed in the brewin receptacle after-thebrewing operation.-

at I claim is a 1. A device for extracting essence from tea-leaves orcoffee, comprising a tube of textile fabric having one end thereof drawninto folds and extended into the body ortion of said tube, a suspendingstring of folded end of said bag and projecting throu h the other endthereof, the last-mengigied end of said tube being also drawn'into o 5,ing the folds on the last-mentioned end of said tube for closing thesame, said suspending string extendlng through said metal strip, that(portion of said suspending string which is isposed within said tubebeing shorter than the len h of the latter- 2. -In a tea-cartri geaccording toclaim 1, said suspending string extending slidably throughsaid metal. strip.
